Different tablets have different side effects on different people. Long term my digestive system can't cope with the type 2 diabetes drug Metformin. I put up with gradually getting worse for about 5 months until I thought I can't take these any longer and was put on the slow release version, which was fine until they doubled my dose and the same thing happened again.

I'm now taking two completely different class of drug which are fine.

Vaccines are generally x1000s safer than the disease they are trying to prevent, they are very safe, but always remember, not totally safe as I found out to my cost & ending up partially sighted. Any faulty drug is reported using a yellow notice which was done by the hospital treating me for blindness where I got uveitis in both my eyes which is virtually unheard of except as the result of a faulty flu vaccine.

Flu vaccines cause life changing problems in about 1 in a million to 2 million doses which equates to 10 to 20 people per year in the UK where the benign version of the virus used boosts your immune system against that variety is bred in vats of egg whites, occasionally a virus will mutate into something nasty & cause a problem, which is what happened to me.

I've been advised never to have this type of flu vaccine again & won't but I have had the anti-pneumonia one since then with no complications.
